I am looking for a FLOSS tool for the Linux terminal that acts similar to
grep, but it should output everything, not just matching lines. But the twist is that the matching terms should be colorized (preferably configurable).
In short, I am looking for a
grep --color PATTERN FILE... on lines with matches and uncolored output for every line without a match.
Doesn't matter if the suggested software is a script or compiled to a binary.
